several calls from this number,

When I answered the call a recorded female voice came up to advertise that "we" (whoever we is) will soon be installing free alarm systems in your (anyone who answers "we's" call) area, press 1.  Dialing the number back gets a recording male voice informing the caller to press 1 to be put on "our" do not call list.  This reeks of scam.  Any company that is trying to telemarket a real product or service will send a real human to offer rebuttals to your objections until you buy or hang up.  Furthermore, the call is from Maine.  The phone is from Texas.  I live in Ohio.  The caller is privy as Mickey Mouse to all things of and pertaining to "you're area".

I also got a call from this number. "Hi this is Jennifer, we'll soon be installing alarm systems in your area. Press 1..."

I don't know how they've gotten my info.

The incoming call is handled by a different company than the original, offending outgoing call.  Regarding that, the outgoing calls from 207-571-8868 are coming from a Brazilian telefraud corp., with registered US offices in Miami.  There's only three courses of action.  File a complaint, using this information, send a cease and desist notice to the registered address and agent (noted below), and/or use the officer contact information to personally call/email these [***] each time they decide they're above the law and that they're entitled to make money defrauding people.  I can find no SSNs for any of these people, so one might enquire about their work status.
